I have fixed this for you. The association was correct, but the DNS was not for Sitebuilder. All new sites are created for use with the new Websitebuilder program. All DNS will be set to direct to these sites. This one can now be used with Sitebuilder desktop, but you might want to give Websitebuilder a try. It is a far better overall option than either version of Sitebuilder. You can use it by creating a new site from the Websites manager page in your Homestead account.
